MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 624,052, dated May 2,1899.

Application filed .Tune 14, 1897.

To a/ZZ whom t may concern:

Be it known that I, JOHN KONAR, residing at Chicago, in the county. ofCook and State of Illinois, have invented certain new and usefulImprovements in Mechanical Movements, of which the following is aspecification.

This invention relates to improvements in a device or mechanism by meansof which a reciprocating power is converted into rotary motion and itconsists in certain peculiarities of the construction, novelarrangement, and operation of the various parts thereof, as will behereinafter more fully set forth and specitically claimed.

The objects of my invention are, first, to provide an inexpensive,simple, and light, but durable,device ot' the above-named character,with any desired number of revolutions by direct draft and without thedead-point, adaptable for foot-power and engines, but especially usefulfor cycles; second, in cycles and other foot-powers an independenttreading` from the speed of the running machines; third, noiselessreciprocation of the machine; fourth, economy in friction andconcentration of parts, having friction for self-protection against dustand dirt and for-economy in lubrication, the journals returning to eachother their surplus of the lubricant, and, fifth, easy access to theinterior, the device being separated by the removal of a single nut.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which- Figure l is a view inelevation, partly in section, taken on line l 2 of Fig. 2, showing thefront of the device applied on the rear hub of a bicycle. Y Figs. 2 and3 are side views in elevation, partly in section, taken on line 3 4 ofFig. l, showing the arrangement and operation of the reciprocatingspring, the ratchet, and its pawl. Fig. et is a top view of the pawl,partly in section, taken on line 5 6 of Fig. 2. Fig. 5 is a view inelevation of one side of a cycle, provided with a hub, as shown in Fig.1, and having a suitable treading attachment for the device; and Fig. 6is a longitudinal sectional view of themachine applied to a rotatingshaft.

Serial No. 640,626. (No model.)

Similar letters refer to like parts throughout the different views ofthe drawings.

The barrel A, with ball-cups con its ends, constitutes a hub of a wheelon the stationary axle' B, having cones Z9 h' and d d. Each end of thehub carries an independent movement or reciprocating device, both beingalike in construction; but one is arranged to the left and the other tothe right. The letters of reference for one sideA are provided withmarks. On both ends of the hub turn caselike pulleys C C, havingjournal-boxes e e', each one bearing on the outer surface of one end ofthe cups c c and havin g j ournal-boxes ff', bearing on cones CZ CV. Thepulleys C C carry on pins g g' the pawls 7L 7L', each being providedwith a sleeve t' and i', respectively, and a hook jj', respectively,extending` taillike from the sleeve. The pawls 71 71. engage withratchet-wheels K K', which are cut in the periphery of one end of thecups ct a. The cones d d/ are provided with longitudinal grooves I I toengage the cornered ends of the springs m m, coiled around the cones d dand secured at the other ends to the hooks j j of the pawls 7t h. Strapsn n', preferably of leather, are wound around the pulleys C C andconnected by rakes p p', which are provided with teeth o to keep thestraps and with fangs or projections z to fit the holes q q in thepulleys C C'. The straps n n lnay be secured at their other ends tolevers r r or another part reciprocated by the power. The spring fm, ifexpanded, has an eccentric pressure on the hookj, and keeps thus thepointed end of the pawl h engaged with the ratchet-wheel K. (See Fig.2.) By pulling the strap n it turns the pulley C and the barrel B andtightens the spring m, which then has a tendency to pull or draw thehook j toward the center. After the unwound strap 'It is set free againthe tightened spring 'm raises the pointed end of the pawl 7L out ofreach of the ratchet-wheel K, (see Fig. 3,) at the same time pulling thepawl 77, back and revolving the pulley C to the starting position,whereby the strap n is wound up again for another pull. The sameoperation is performed when power is applied to the strap n', which willkeep the cycle in continuous motion. The spring 'm serves thus for twopur- IOO p ture.

poses-first, reeiprocation of the machine, and ,second, avoidance ofclicking and friction of pawl 7L against ratchet-wheel K duringrecprocation and yet engaging the pawl with the ratchet-wheel again atthe starting-point. 'lhe pulleys C C' serve also as dust-caps and asoil-retainers. rlhey may he cast, aluminium giving suflicient strengthfor this strucequipped with ball-bearings. `l'ly'taking off one of thecones (l clthe combination on both ends of the hub can be separated.

'lhe described machine has a suit-able combination for the rear hub of abicycle. Fig. 5 shows a bicycle provided and arranged for this purpose.Close to the head D thereof is located on the frame the hanger E, towhich are pivotally secured the levers o' fr. These levers are providedat their rear ends with pedals or stirrups s aud are connected with thestraps ln. a, reaching the pulleys C C. 'lhe broken lilies X show thearc the stirrups describe when trod. The straps 1t n' may be connectedin a suitable manner with the levers r o", so as to be adjusted nearerto or farther from the rotation center of thelevers for change of speed.

Fig. G shows the machine in combination with a rotating shaft F, whichcarries the ratchet-wheel K2 and turns in the journalbox (Z2, secured inthe framing G. The pulley C2 is journaled on the rotating shaft F and outhe box d2 and carries on the pin g2 the pawl 71,2 to engage theratchet-wheel K2. The pawl h2 is provided with a Sleeve 2 and a hooklike the hook 7" on the pawl K to engage the eccentric end of the springm2, which fits with its cornered inner end in the longitudinal groove Z2in the journal-box (Z2. In the same manner as above described withreference to the straps n 71.' is the strap n2, secured at one end tothe pulley C2 and at the other maybe connected with a pedal or its leveror with a reciprocating part of an engine.

'lhe journal-boxes c c/ andff may be.

One or more rotating machines of the described constructions can beapplied with one hub orl with one rotating shaft in cycles, lathes,sewing-machines, bellows for forges, 8:0.; but if one movement only isemployed a balance-wheel on the shaft should be employed to keepcontinuous motion.

Having thus fully described Inyinvention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In a mechanical movement, the combination of a pawl pivotally securedto a pulley and having engaging means near one of its ends, with aspring located around the axle or shaft and secured at one of its endstoA a fixed part and having its other end attached to the saidengaging'means of the pawl, substantially as described.

2. The combination with an axle or shaft, of a pulley mounted thereonand carrying a pawl, a ratchet-wheel within the pulley to engage thepawl, a spring encircling the shaft and secured at one of its ends toone end of the pawl, and at its other end to a fixed part, p

and a strap or its equivalent secured at one of its ends to the pulleyand encircling the same and at its other end to a reciprocating part,substantially as described.

3. The combination with the barrel A, of the shaft B passingtherethrough, the ratchetwheels K, K', the cones d, d', provided withgrooves l, W, the pulleys C, C', having journals e, e', and f,f, andcarrying pins g, g', the pawls 7L, 7L', secured on said pins and havingthe sleeves t, t", provided with hooks 3,7, the springs m, m',encircling the shaft and secured at one of their ends in the slots ofthe cones d, d', and at their outer ends to the hooksj, j', of thepawls, and means for turning the pulleys, substantially as described.
